2006年-2012年深圳市污染减排对降水及空气质量的影响研究

Impacts of Pollution Reduction on Precipitation and Ambient Air Quality in Shenzhen during 2006-2012

本文以2006年-2012年深圳市环境空气质量监测资料数据为依据,探讨了污染减排对城市降水和空气质量的影响,阐述了污染减排取得的环境效益,为深圳市下一步污染治理和环境管理提供了科学依据。结果表明,七年间深圳市酸雨频率下降27%,二氧化硫年均值下降66.7%,二氧化氮年均值下降24.5%,可吸入颗粒物年均值下降15.6%,综合污染指数下降33.1%,霾天数下降47.6%,空气质量Ⅰ级(优)天数从2006年的160天增加至2012年的208天。

The impacts of air pollution reduction on precipitation and ambient air quality in Shenzhen City was analyzed on the basis of monitoring data from 2006 to 2012 on urban ambient air quality. The environmental benefits were expounded, which would provide reference for decision making of pollution abatement and environmental management in future. Results indicated that, the frequency of acid rain descended 27% , the annual average of SO： descended 66. 7% , the annual average of NO2 de- scended 24. 5% , the annual average of inhalable particulate matter descended 15. 6% , the comprehensive pollution index descen- ded 33. 1%, the haze days descended 47.6%, the air quality days of I level in 2012 were increased to 208 days compared with 160 day in 2006.
